I finished Plague 2: Attack of the Rats. Overall it was a good game, but not without its problems. Let's start with the positives.
This is a great looking game, on par with anything from a AAA studio. Sound design is equally great and the voice acting is terrific. Top notch production value all around, you'd have no idea this was made by a AA studio. I can only comment on the xXxBOxXx version of the game, but it ran nearly flawlessly. I had one hiccup about 2/3 of the way through where the game suddenly froze, although I could still hear dialogue. I thought for sure it was about to crash, but after about 5 seconds it started moving again and everything was fine. Outside of that one freeze there were no crashes, no stutters, everything ran buttery smooth.
The vast majority of the gameplay was quite fun. It was mostly a stealth game with light puzzle elements and figuring out how to get through areas was a good time. I mostly took an approach where I tried to ghost areas and kill as few soldiers as possible, except one section with slavers, I went out of my way to kill them. The run for your life sections were always fun and the two turret sections decent enough. The parts where I got to walk around without any threats were also welcome changes of pace. I liked all the gameplay except... Well, let's get to the negatives.
The game has forced combat sections where you are essentially locked in an arena and have to kill all the enemies. For most of the game, these are few and very far between, which is great. Early on, they're fairly short, but eventually they throw more and more waves of enemies at you. These were far and away the worst parts of the game IMHO. The combat wasn't bad, but it wasn't fun either, and it became a real slog when the combat just kept going and going. Eventually, I just dropped the difficulty down to narrative to get through the combat sections as quickly as possible, then I bumped it back to normal when done. Toward the last quarter of the game the frequency of forced combat increases drastically and that chunk of the game sucks.
Also, I feel the game was a bit too long. This is, of course, going to be very subjective. Some people are of the opinion that more is always better, I disagree. This game definitely outstayed its welcome. Not massively so, but the last few hours I was definitely just wanting it to end, rather than looking forward to what happens next.
Now, let's talk about the story. It was told well and the pacing was great, even if the story went on too long. However, the story itself... I have to go into major spoilers from here on. You have been warned.
